Utilization
CompilerEnvironment
- cargo 1.51.0 (43b129a20 2021-03-16)
First download cargo, then compile the code
cargo build --release
There are two points here to pay attention:
- In the analysis article, if your system has patch installed a KB, you need to replace 200 lines of code to 199, and vice versa.
- The second need to use PowerShell to perform exe，And need to have
winlogon.exeThis process is running，The location of this process is in theC:\Windows\System32directory
Then run directly in Windows 7 SP1 X64
